DAVID H. NATION, OF ALBANY, NEW YORK.

STOVE-GRATE.

To all whom it may concern:

Be it known that I, DAVID H. NATION, of Albany, in the county of Albanyand State of New York, have invented a new and useful improvement in theconstruction of a stove-grate, by means of which the spindle or shaftcast to the same is made to perform the double purpose of shaking anddumping the fuel, thereby dispensing with the use of separatecontrivances for each purpose and producing a less complicated gratethan others, consequently lessening the expense of construction, andpossessing other advantages which will be herein clearly specified.

The nature of my invention consists in suspending the spindle or shaftcast to the grate, in two loops or elongated bearings which are securedby means of bolts to a circular frame surrounding said grate, and aremade of sufficient length to allow the spindle or shaft to reciprocatefreely horizontally, their upper edges being made thin to lessenfriction and prevent dirt or cinders from lodging thereon. These loopsor elongated bearings can be easily detached from the frame for thepurpose of removing the grate without disturbing the stove bricks orlining. In ordinary grates with fixed bearings or centers a very smallopening is provided for dumping as the 'shaft is placed so much at oneside to overbalance. But by my arrangement the grate while being dumpedslides to the ends of the openings in the loops or elongated bearingsand gives an opening of about two thirds of the whole space, the spindleor shaft being provided with sufficient end play between the shouldersto clear itself from clinkers or other obstructions. A slot or openingis cut in the base through which the shaft or spindle projects, it ismade long enough to allow it to reciprocate freely, a sliding plateprovided with a hole to receive the shaft or spindle covers this openingit is supported and kept in place by guides cast on the base and slideswith the motion of the shaft or spindle thereby effectually preventingthe escape of dust into the room while shaking the grate and dispensingwith the use of a door thereby lessening the expense of mounting. Theouter end of the shaft or spindle is squared to fit a socket formed onone end of a lever or handle, the other end is made with an offsetforming a crank which is also representation of the same, like letterscorresponding with like parts.

Figure 1, represents a side elevation of the stove. Fig. 2, 1s aperspective view of the grate and circular frame removed from the stoveto show the loops or elongated bearings. Fig. 3, is a side elevationwith part of the base broken away to show the shaft or spindle and theloops or elongated bearings, the lever or handle is shown in positionfor dumping the grate. Fig. 4, is a plan of the same showing theposition of the handle or lever for shaking the grate. Fig. 5, is alongitudinal section with the grate dumped.

A Figs. 1, 3, 4 and 5, represents the base of a stove.

B is a circular frame surrounding the grate C and on which is cast theprojections c, 0, one of which rests on a flange (6) cast to the frame Bto support the grate C.

D D is the shaft or spindle cast to the grate and suspended in theelongated bearings or loops E E and in which it moves freely for thepurpose of agitating the grate C.

F is a sliding plate which covers an open ing in the base A throughwhich the shaft or spindle D passes. G G are the guides to keep it inplace.

H is the handle or lever provided with a socket I on one end to fit thesquared part of the shaft D the other end is bent to form a crank Jwhich is used for dumping the grate.

I claim 1. The loops or elongated bearings E E in combination with thereciprocating shaft or spindle D substantially and for the purposespecified.

2. The sliding plate F, when used in combination with the elongatedbearings (E,) and the shaft or spindle D, substantially as and for thepurpose specified.
